IDENTIFICATION OF MULTIVARIABLE SYSTEMS IN THE TRANSFER-FUNCTION MATRIX FORM
H. El‐Sherief, Nandan Kumar Sinha · Journal of Cybernetics · 1979
A recursive algorithm is presented for estimating the parameters of linear discrete-time multivariable systems using the transfer-function matrix representation. The proposed algorithm decomposes the system into sub systems such that the parameters of each subsystem are estimated independently by a recursive least squares method. Also, a technique is pro posed for determining the order of the system offline when it is unknown. Results of simulation are presented comparing this algorithm with an earlier method.
